Has anyone else have to deal with a radiator fan motor going out?

My 04 vette's dash lit up saying that my engine was overheating . People are saying it's the radiator fan motor but I have no experience in that field since I tend not to mess with electric based repairs. Would anyone happen to know if this is a easy repair or should I just take it somewhere?

If you are mechanically inclined its something that you should be able to do yourself. Was able to find some instructions online from the service manual. There are also some tutorials/guides up on YouTube.

Overheating is a common issue on older vet models, so there are quite a few dedicated boards you can go too that may have more direct experience with replacement. If you were go to a shop for replacement you are probably looking at a grand for parts and labor.

Going to independent mechanic shops that specialize in GM products like your 04 Corvette is probably the easiest and most effective method. Aside from that, check a C7 board.

If you do some searching on google there are plenty of other boards with threads specifically about this issue. Its not uncommon for early 2000 models to run into issues with heat management.

That might explain why you rarely see them around aside from car meets.

I used to have a C7 but sold it for a Jaguar F-Type. Anyone whose been around C7's long enough, doesn't want anything to do with them.

I realized its a challenge for some automakers to like Chevrolet to keep up in this segment. Sales have been on a decline drastically within recent years.

We don't have to look far to see why, its MSRP range has stiff competition that's more inline with the times, hence the C8's evolution.
